is allocation unit size the size of the partition, or does that have to do with the sector size or something...

The maximum default cluster size under Windows XP is 4 kilobytes (KB) because NTFS file compression is not possible on drives with a larger allocation size. The Format utility never uses clusters that are larger than 4 KB unless you specifically override that default either by using the /A: option for command-line formatting or by specifying a larger cluster size in the Format dialog box in Disk Management.

I read that from http://support.microsoft.com/kb/314878/ but I don't fully understand it. From what this page says, im lead to believe that it changes the cluster size, which changes the volume size. The largest it will let me do under NTFS is 64K (remember that it only lets me choose NTFS; for fat32 I have to use the DOS Format command). What size would that mean I should use for fat32 using the format command?

Originally posted here by muert0 I'm kind of tired of dealing with this because I don't think you are trying my suggestions. Maybe someone else will help you or maybe you will just have to find a good local shop to take it to.

I really do appreciate all this help you have been giving me, and I do understand. I promise you that I have tried everything you told me to, and nothing seems to work. It won't let me do Fat32 in windows regardless of the allocation unit size that I try. It only says that I have 149.05GB in Windows (don't remember what linux said). Linux won't let me add a partition in Fat32. I don't even know what to do. I might just give up and run the program that resets it to its origonal full Fat32 format.

i'm running a diagnostics program right now to see if there is any damage.
I will post an update when it is done. (45 min to go.)
